SSRS表达式转换为UTC

Question

I have tried my best to convert one textbox to UTC using the SSRS expression. It is not converting it. Is there any settings to configure before this code can work ? i used these two code below. Nothing works!

=TimezoneInfo.ConvertTimetoUtc(CDate(Fields!Starttime.Value))    

=DateTime.SpecifyKind(Fields!Starttime.Value, DateTimeKind.UTC)

Answer 1

Use the expression below

=Fields!Starttime.Value.ToUniversalTime()
